Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Inhibition of soil nitrogen transformation by soil micro-organisms was examined in a study with TDCP conducted voluntarily by industry (van Ginkel, 2005). A 28-day NOEC of ≥128 mg/kg wet weight (no inhibition at the highest concentration tested) was determined in the test.
Key value for chemical safety assessment
- Long-term EC10 or NOEC for soil microorganisms:
- 128 mg/kg soil dw
Additional information
Due to the structural similarity of TDCP to TCPP, their similar physico-chemical properties and their lack of toxicity to soil micro-organisms, it is considered justifiable to read-across the long-term soil nitrogen transformation effects data from TDCP to TCPP. This was agreed at TCNES III 05.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
